This area is for any observations or conclusions that you would like to note.

We have observed that our nanogels are sinking to the bottom of the beaker and clumping together during the freeze-thaw method. We are interested in changing a few variables. First, we will try flash freezing the solution before it is ready to be placed in the freezer for the first cycle using liquid nitrogen. This will freeze the gels in whatever position they may be in and will hopefully stop them from collecting at the bottom of the beaker. Second, we are interested in using an oil with a higher freezing point. The mineral oil we are using does not freeze very readily in the -20°C environment. Saffron oil will be our next choice.

Use categories like tags. Change the "Course" category to the one corresponding to your course. The "Miscellaneous" tag can be used for particular experiments, as instructed by your professor. Please be sure to change or delete this tag as required so that the categories remain well organized.
